Application filed August 2,V

byV weather proofing seamcoversthatpermitrelative `movement of vsaid roof sheets VIto a limited extent so as to beabletojaccommod'ate themselves to the car body,

The principal objectof-the present ini/'enf tion is an improved seam construction thatA vwill .Secure-a pivotal movement of the roof, sheets" whenever` there lis ymovement thereof.-

Other objects are simplicity and 'cheapness ofconstruction, compactness and economy vin design and ease of assembly. rlhe invention consists principally in connecting the spaced margins oit-adjacent rooil sheets bymeans of a Weather prootingfseam; cover that 'has a separate pivotal connection with `each or said sheets. The invention tnrtherconsists in the parts and in the combinations and arrangements of parts hereinatter described andclaimed.'`

As shown in thev drawing, the seam covers are strengthened by ribs 24 that extend yfrom the inner edge of the bosses v22 to the side walls of said covers. By this arrangement, the roof sheets are pivotally held down on the roof vby the cooperating pivot bosses on the ridge ends of said sheets and thebaseflanges of the ridge seam cov-V y ers and are thus adapted to accommodate themselves to the distortions of the car body by pivoting or sluing about points locatedk j rangement is thatit secures a sluing or pivotal movement of roof sheets, Ywhich are spaced apart along their ridge margins,

What I claim is:

l. A flexible Vcar roof comprising roofk sheets spaced apart along the adjacent mar# gms, a seam cover` covering the adjacent marginal portions of said sheets, and-a separate pivotal connection between said seam cover and each of said roof sheets, said connection preventing bodily movement of said sheets longitudinally of said seam cover.

V6. A flexible car roof comprising .roof sheets spaced apart along their adjacent margins and provided with up'standingepivots near said margins, and a seam cover covering the adjacent .margins of said sheets and having` outstanding base flanges vprovided with pivotbearingsl adapted to receive the pivot bosses of said roof sheets.
